Fiberglass Grating
High quality, well designed, pultruded grating, which resembles metal bar grating, is stronger, lighter, equally corrosion resistant, and in most cases, is less expensive than molded grating. Additionally, pultruded grating comes in larger panels and can be built to custom panel sizes. In most applications, pultruded fiberglass grating will represent the best product and the lowest price.
Molded fiberglass grating has equal strength in both directions and is made with square or rectangular grid patterns. Since it was developed much earlier than pultruded grating, it is widely used and performs well in many applications.
